The lock, which is designated generally as '10,isplacedu-pon the side '11 of a railway car or other receptacle. Upon the door 12 of the car is hinged the usual hasp 13, having a slot :14, which catches-over a lug 15 projecting froma front wall 16-o f-the look. A pin 17 may be dropped through a hole 18 in the lug, thereby locking the hasp. *Saidpin is guided up and down in a perforation 22 formed in the flooring of the lockho'using. Flt-also has-an upperguide in a hole 19 which is formed in the bottom of a compartment 20 projecting forwardly from the loclnfiFig u're -6,-the floo r of said compartment 20 performing the function of a rigid lug to eooperate with said lug 15 for retaining the hasp, the tongue of which is eonfined between said lug 15, and compartment 20. I One of the objects-of the invention is to provide a door-lock which is both strong and compact; and in "order to aneet the requirement for compactness the difficulty due to the great "length of the usual pin is'oyercome by bending thelpin into the form of an inverted U, of which the longer leg or portion 21 is used mainly for guiding purposes, as it works in perforation 22 formed in the flooring 23 of the lock. This leg 21 projects down beyond the bottom of the lock, to form a hand-hold, whereby thefentire ll sh'a-ped hasp-pin may be raised, whenever it is desired to either open or close the car; and it may be dropped in order to secure the liasp. The cross-piece 2 L of the U rests upon the bot-tom of the compartment-20. A

One-side edge of the lOClI-lIOllSlng is in the. form of a vertical plate 25, standing at'r-i-ght angles to the side of the car 11,'and forming an abutment against which the car door 12 is closed. The long leg 21 of the U pin may extend a little below the abutment 25, for convenience of the operator in finding the pin in the dark; and the flooring at 23 may be at a sufiicient elevation to permit the necessary upward range of movement of the pin while the leg 21 still remains caught in the guiding hole 22. The guiding holes 22, 19 cooperate to guide the entire pin unit, while the locking pin 17-, being restricted by the hole 19, prevents rotation of the unit about the leg 21 as an axis. As viewed from the inner side, it will be seen that the interior of the compartment 20 forms a groove 26 in the front Wall 16, see Figure 8. The pin is kept withinthe groove by means of a fixed guiding arm 27 forming part of the framework.

Another advantage gained by bending the hasplockingpin into U form, is that a groove or looking shoulder 28 may be formed in the leg 21., into or over which may catch a book 29 forming a tumbler which is pivoted at 30 upon the framework, and counterweighted at 31 to keep the hook released.

After the hasp has been'closed and the pin 17 has been dropped into locking position, a handle 32 upon said tumbler 29 maybe lifted, thereby swinging the tumbler or hook 29 over the shoulder 28 upon the locking pin 21. Other forms of tumbler than the book form may be employed, and other means for holding the tumbler released; and a finger- .piece may be provided otherwise than upon the weighted arm 31.

The tumbler itself is retained in locking position by means of a destructible seal, designated generally 'as 33, which fits in a slot 3% formed in the tumbler 31. It can be passed into the slot when the tumbler is in looking position, but not when it is in the open position, seen at Figure 12. This seal is held-in a chute 42, 43 against edgewise displacement, and he ce retains the tumbler in locking position. This seal is visible through a vertical front window 35, which closes an opening36 in the front wall of the lock, and enables the individual numbers 37 of the seal to be read, as well as other data thereon, and permits generally an inspection ofth'e main portion of the seal to discover if it has been tampered with.

The seal may have a reduced or bluntly pointed leading end 39, Figure '5, for'ease of introduction in a seal-slot or perforation 40 formed in the bottom 41 of the lock.

Rising from the slot 10 is a seal-chute within the lock, including a rear wall l2 and side guidi'ng walls 43. Just suflicien't space is left-in the chute between theback 42 and the glass wind'owpane or light 35, to permit the Epassage of the seal with its raised figures and letters 37, 38. llhe walls 43 interlock with-tlie'seal, to enable the seal to lock the tumbler 29 against movement.

The chute and the seal therein are con-.-

' seal nearly rises to the height of the slot- 34 in the. tumbler, it encounters a fixed deflector 44 within the lock, which may beset at an the teeth of gear 51 middlev of the seal.

angle of say 30 degrees tothe rising seal. The seal-chute at its upper portion may be inclined a-little rearwardly. Figure l, so as to present the point of the seal at a more favorable angle to the fixed deflector 44. It,

will be noticed that one or more recesses 45 may be cutin the rear face of the glass pane 35, to accommodate the forks 44 which form the deflector, The deflector is forked so as to clear the raisedportions 37, "38 along the At the top, the deflector maybe fastened by a. screw 46to the rear of a bracket 47, which includes a rear wall 48, forming'a backing for thechute and also includes a frame 49 for the window. l

d When the leading end of the seal encounters the deflector 44, it is fixed or bent toward the left atFigure 1, and takes a curved path andenters the bight of corrugating rolls 50, 51, having intermeshing teeth 52, by which the seal is corrugated throughout its length as at 53. The rolls are rotatedby a key or handle 54 that is fixed upon the end of a shaft 55, which is connected by a oneway clutch 56 to :a gear-shaft 57 having gear 51 thereon. Any attempt to return this seal by means of the handle, 54 would befruit .less, because the one-way clutch 56 renders the hand-wheel 54 incapable of rotating the gears. Moreover, a spring-dog 58 engages to prevent it from being rotated backwardly. r a

In using the device, the car door 12 is closed against the abutment-plate. 25 of the lock, and by means of thependent long leg 21 the hasp-pin 17 is lifted clear of the lug 15, whereupon the has'p 13 is closed over said lug 15, and then the hasp-pin is dropped, therebyzretaining the hasp.v At this time the tumbler 29, 31 is in normal withdrawn position. By means of the finger-piece 32 said tumbler is now swung over into locking position, see Figurefi, with the hook 29 catching over the shoulder. or in the slot 28 formed in the long leg 21 of the. hasp-pin. At this time the, slot 34 inthe tumbler is in line with the seal-chute 42, 43. They Operator then thrusts upja sea-l lock; .The seal thereforeinterlocks with the tumbler, so that. the car door cannot be opened, and it is the intention that'a new seal cannot'be used untilthe first one has been destroyed and ejected by means of said rolls;

the railroad operative not beingmprovided with duplicatenumbered seals, and the inser tion of a fresh seal having the wrong number thereon leading to detection. l

7 To go more into detail, it will be seen that in the normal position of the members, 7 the hasp l3 hangs loosely upon the car door, and the hasp-pin 17 is in its bottom position. The tumbler 29, by reason of its shape'and its pivoting is so weighted as to bring its normal.

positionto the left, with the handle 32-protruding down through the bottom,.this protrudingportion being found in the hand opening175 at the left of the lock. l v

The car door is now closed, and with the left hand thelong leg 21' of the U-shaped 'hasp-pinis raised as far as it will go. While it is held in that position, the hasp 13.is placed over the haspelug 15,'by, using the right hand. The left hand now permits the hasp-pin to drop,the short leg of the hasppin dropping through the hasp-lug in front of the hasp, thereby preventing the hasp from opening. While this doesnot actually look the door, itidoes prevent the door from working open. The left hand is now placed in the hand opening at the left under side ofthe lock, and presses the tumbler-handle 32 up as far as itwill go, thus rocking the tumbler 29 so that it enters the lockinggroove 28 on the hasp-pin. While the tumbler is held in this locking position by the left hand, the right hand introduces a check-seal 33 into the slotway 40, pushing it right up and through the deflector 108, 44, and through the tumbler slot 34. This seals the locking bolt in its locked position. The left handcan-now be released and placed on the turn handle 54,

' and turns the handle to the left, or away from the operator. At the same time the right hand presses the check-seal 33 farther up into the slot-way 40, and the rotated gears will now take hold and draw the check-seal entirely within the look, at which time the operator stops turning the key or handle 54. As the hasp-pin 17 prevents the haspl13 from being opened, and the tumbler 29 is in locked engagement with the groove 28 in the hasppin 21, and the check-seal 33 locksthe sea-llocking bolt 29 against falling back to its normal position,and the gears '50, 51 are looking the check-seal, and the ratchets 56 and detent 58 lock the gears against reverse movement, it will be seen that thecar is actually locked and sealed, and cannot be opened except by the advance and removal of the check-seal 33. The seal is sufficiently strong to retain the tumbler in its locking position, Figure 6, and the tumbler is so positioned that the jarring, due to the traveling of the railway ca does not appreciably injure. the seal. Assuming that the record, as per indicia on the seal, has been duly registered by the seal takers, etc., the car is placed at the platform ready to be opened. This ,isgaccomplished by merely turning the handle 54 to the left, thus sending the check-seal through the gears, and ejecting the same th'rough'c'hute 101 into the inside of the car, in a cut up mutilated condition. This operation o'f'e'jecting the check-seal releases the tumbler 29, which settles back into its normal position, and by so doing withdraws from looking the groove or shoulder 28 in the hasp-pin 21,'thus permitting the latter to be raised, and the hasp to be removed from the hasp-lug, and the door opened. When the tumbler is in a normalpos'ition, the seal-slot 34: isentirely out of register with the seal slo'tway 42, and for that reason no sealof any de' scription can find its way between the gears; and it is for this reason that the push end 32 of the tumbler is hidden, thus preventing a large percentage of unauthorized persons from perceiving the manner of operation.

A tanopy 59 may form an extension of the top of the housing at one side of the latter, and overhang the window and the ha'sp13, hasp-pin 17 and. other parts, to protect the'm from the weather.

The U-shaped hasp-pin 17, 21, 24 is mainly confined within the housing to protect it from burglars as well as the weather.

The housing may be placed along the side wall of the car and secured by bolts 60, 61, 62, the bolt 60 passing through a flange 64 extending above the housing, and the bolts 61, 62 passing through the wall of the vertical compartment 20 which contains the hasp-pin, and bolt 63 passing through an ear 65 at one side of the housing. The housing is open or unprovided with a wall at its rear side, but the edges of its side walls are bolted'ag'ains't the side of the car, thus completing the enclosure for the mechanism.

At its lower portion there may be formed upon the housing a projecting lug 66, ha'v ingtherein a hole 67, for convenience in attaching a padlock or other means for greater security in looking the car door. This hole may also be used as a device in which to hang bale hooks or tally strips temporarily.

There may be provided upon the casing a projecting guide 68, to overlap the car door and to guide the door when closing. This part 68 may also serve as a support for the door, as it will relieve the hasp of strain in the event of the load within the carshifting against the car door. The upper and lower extension-plates 25 of the side wall of the housing are stiffened by the upper and lower flanges 64, 69 atthe rear of the boxing, and solidly withstand the edgewise thrust of the car door after the same is locked and when the train is in motion.

The seal-receiving slot 10 is in the very bottom of the housing, where it is safe from the weather, the seal being thrust endwise upwardly into said slot, Figures land 4.

- At the leading end of each seal, one corner is cut off diagonally at 70, giving a special sha e to the end of the seal, rendering it irreversible. This asymmetrical end fits in a groove or depresion 71 formed on the under side of the box floor 41, Figure 4. When the seal is properly presented to this groove, it is found to fit, and the groove may guide the user in slipping the seal along the floor until it reaches the slot 40 and is pushed up therein. The seal is intended to go into the look only one way. If the seal were turned around, its tip would not fit in the groove 71, and the user would thereby be informed that the seal was not properly positioned, even in the darkness. The same difliculty would happen if it was attempted to insert theseal wrong end up. The grooving or shaping of the bottom of the box 41 is therefore such that it will easily'receive and lead or guide the seal to the slot, when the advance end of the seal has been properly presented.

The groovepoition of the slot is bordered by a ledge 72, which is provided to assist the fingers of'the operator in feeling for the slot; and this ledge may be continued at 73 at the side 16 of the boxing. The side ledge 7 3 may be arched to form protection against the weather.

A hand opening 75 is provided in the bottom of the box at its left-hand portion, as a convenience in reaching and locating the lower end 32 of the hook 29, forthe purpose of entering the hook in the slot 28, prior toinserting theseal 33 for maintaining the hook in its seal-locking position.

The hasp-pin is U-shaped, the shorter leg to pass through the hasp-lug 15, and at the end of the short leg of the hasp-pin is provided a slot 76, which slot registers with the slot 67 in the hasp-pin registering lug, for

convenience in attaching a padlock if desired. The longer leg 21 is mostly hidden inside oft'he lock, and the lower portion of it is raised and lowered through the hole 22 provided for that purpose in the bottom of the box. A hole 77 is provided in the extreme bottom end of the hasp-pin, for the purpose of entering a bale hook or a like instrument to pull the hasp-piin down, shouldit stick.

On the confined or hidden portion of the hasp-pinthe locking groove 28 is so positioned as to make burglar access impossible.

The seal-receiving, seal-destroying and seal-ejecting unit 80 is provided on the left side of the lock. This unit is inserted into the box from the rear,before the box or lock carrying it is attached to the car; said box being entirely open on its rear side, which is placed agains't'the' car wall. Said'seal-receiving, destroying andejecting unit includes a box-like frame 81 which is provided with an upper right-hand corner hole and a bottom left'hand corner hole through the body of the unit, through which long machine screws 7 8 and 7 9 are inserted for securing the unit detachably to the inside of the front wall 16 of the box a hole or slot 85 isprovided, the

slot being open in the rear, to permit assembly of the unit within the main boxing. The

unit includes a slanting wall-portion 86 which is so shaped as to close up the opening 85 in the bottomof the lock, so that burglar manipulation ,of the interior of the lock from'this side is made impossible.

An extension'87 is provided on the right of the unit 80,'into which pivot 30 is placed; and also on the right is an upper projecting integral arm 27 for the purposeof keeping the U-shapcd hasp-pin 21 in position. In the arm is threaded a set-screwt89, which serves as an adjustmentfor the proper general positioning of this unit in the lock. The screw is provided with a nut '90.

On the back of the unit, and cast integral with the frame. thereof, is a boss 91 provided with a slot 92 through which the.

mutilated seal is ejected.

The walls of the unit 80 serve as a rest or seat for the seal-guide. Intheupper portion of the unit 80 there is provided an opening 93 into which are arranged the upper and lower meshed gears 50, 51, the upper gear being an idler mounted upon a shaft 94, upon which also are mounted, on either side of the gear, hardened collars 95, 96, Figure 121 The lower gear 51 is keyedon shaft 57,the forward end of which shaft is enlarged and forms a ratchet-clutch, or

back-check 56, Figure 2. JMeshing with this ratchet and taking its bearing in the thick boss, is another clutch or ratchet197, extending its shaft-portion 55 outside of the boss 82, and to its extending end is secured the turn handle 54. l/Vhen the outer ratchetmember 97 is idly turned in clockwise direc-,

tion, the ratchet 56*remains stationary, and shaft 55 is forced outwardly A screw or stop- 99 which is placed in the path of the outer ratchet, prevents the same from being withdrawn too far. The clutch-members are so made asto permit of the turning of the mutilating gears in one way only; and a turn on the handle in the reverse direction merely turns the handle-ratchet idly. As a. further lock against a reverse movement of the gears, theflat detent 58, which is positioned against the lower gear 51, isheld in position by a screw100 in the lower portion of unit80. c j l Between the two gear shafts, and soposi- V tioned as to receive the destroyed seal as the same is ejected from the gears, is the chute 101, which projects intoseal-ejecting boss 91 at the back of the seal-unit 80. 1

Through slot 34in the seal-locking bolt or tumbler, the seal enters the gears.- At the lower left end of the bolt or hook 29. is the extended portion 32 forming a handle, which passes through a hole102 in the wall of the unit at the left, Figures 2, 12. The

bottom right portion ofthis bolt is provided with a pivot-hole through which the pivot 30 extends. on its seat, and is enclosed by the Walls pro vided to receive the same; After the win.- dowpane 35 is placed in position, the entire The seal slot-way 47 is placed 1 unit is securely screwed to the front wall f of the lock by screws 78, 7 9. Unit 80 is provided with front flanges 103, 104, 105, for the purpose of seating against the front walls of the lock or boxing. Rear flange 106 is flush with the rear edges of the boxing walls 10. Between the flanges 105 is confined the vertical frame 49, for the purpose of guiding the seal. This frame also encloses the windowpane 35. The lower end of chute 42 registers with the seal-slot 40 in the casting, and is flared outwardly at 107 for the purpose of assisting easyinsertion of the seal. The upper end of the chute 42 is turned back at 108 to helpbend and guide theseal back through the slot 34 in the seallocking bolt29. In the back wall 48 of frame 49 there is a cutout 109, through which extends forwardly the two prongdeflector 44, which co-operates with 108 in flexing or bending and guiding the seal through slot 34 in the seal-locking bolt 29, and in introducing the seal to the mesh ofthe'gears. The window is notched on the rear face. at 45, into which 1 notches the prongs 44 extend, thus insuring the seal being deflected backward to the gears. I

The window 35 is provided with inturned points 74 upon its opposite sides, one point higher than the other. These points will make itdifrlcult for a burglar to insert a new glass, if he should remove the original glass. "At Figure 13 is shown-one form of seal,

having its leading end39 cut away at one corner 70, and having ribs 110 extending its entire length, one on each side of the indicia space. The shaped corner 70-permits entry of the seal into the slot-way, and at the same time insures the'proper placing of the seal in reading position.

1 Figure 14 shows that if desired both lead ing corners may be cutaway, as at 7 O, in some cases.

Figure 15 illustrates a yielding obstruction which will permit the entry of one form of seal,as for example Figure 14,but will prevent the' introduction of a spurious seal having a square leading end. This device is in n u l which could; not thus be pushed to one side, and hence it would serve as an obstruction to prevent the seal from being introduced. An additional pawl 112 could be provided on the oppositezside of the seal slot-way, and each pawlv could be double headed, as at 113, and both pawls could be made of one strip of metalg. or of a single wire, as illustrated. Theseal could be provided with an embossed arrow-headv 114, to indicate its leading, end, and also to indicate the upper side of the seal.

lit Figure 16 the windowpane 35 is shown as provided with parallel vertical grooves 115, in which may fit the seal-ribs 110 seen at Figure 13. It will beseen that if the orig.- inal glass pane should be broken. or removed, and: a new one substituted. without having said grooves 115, it wouldbecomeimpossible to insert a seal, since the ribs 110 would be obstructed by the lower end of the glass pane; Moreover, this shaping of the glass pane would be effective in many instances in preventing'th'e insertion of a. spurious seaL.

At Figures 17 and 18 is shown an intercepter 116 pivoted at 117in the housing at the seal-chute, in position to intercept the lead ng end 118 of the seal seen at Figure 17 this interceptor being in-the form of atongue whose tip isheld against the inner face of the glass pane 35 by a spring 119-. This intercepter 116 may be forced away from the paneby meansof cams120, which maybe pressed in the leading end of the seal, and may have beveled leading ends, to engage bevels 121 which are provided upon downwardly-exten'ding'arms 122, provided upon said intercept-er 116. As the seal is thrust up, theleading bevels 129' engage the bevels 121, and swing the arms 122 away from the glass, to gether with theinterceptingtongue 116. These cams have dwell or rib portions 123 extending'along the seal, to maintain the interceptor 116: away from the glass until the recessed leading end118 inserts itself between the glass and. the tongue 1161 Spurious seals will be" intercepted by the tongue 116', because there is nothing'to lift it up from the glass. The bevels or teeth 121 do not touch the glass, but leave a clearance, which would permit the passage of a spurious seal, which would then be caughtupon theton'guellt and arrest-ed.

Figure 19 is a form of interceptor which may be used with the seal shown at Figure 13and' elsewhere. This interceptor is in the formiof asingle pawl124, pivoted at 125 and pressed by a spring'126 to normal position. The pawl has a hovel 12? to enable the bevel 70 or the seal to press the pawl to one side, so that the seal may freely pass up into the chute 12; If it should be attempted to insert the seal the wrong vay' around, or if a spurious'seal: should be ii....erted, the same would engage the abrupt end 128 of the pawl and be arrested-t At Figures 5 and 7 is shown one form of seal, which is mainly unstilfened, so that it may freely pass around the bend at 108,.Figure 1. At its lower end the seal isprovided with s aecial short, longitudinal stiifening flanges 129, which convert this end of the seal into a handle, for convenience in holding and inserting the seal, as it may be pressed up by the fingers without liability of orumpling, buckling or bending the seal. These finger supports 129 may remain below the housingand be: of use in pressing up the seal, until it gets back of the bend and reaches the bite of the drawing rolls, as at Figure 1. These ribs 129 are preferably placed on opposite sides'of the seaLasshown, and the result is that the chute, at Figure 7, is completely filled by the seal, so that it is impossible to insert a second seal while the'first one remains in" the chute.

The same=structure is seen: at Figure 9, except that the stiiiening ribs which form the finger-piece are on the same side of the seal as at- 130,.while a single longitudinal stiffening rib 181 may be formed upon the opposite side 05 the sealto extend the entire length thereof, or as far as'desired'.

Each seal may be also provided with miscellaneous thickening, means, in the form of buttons or cups 132 pressed in the seal, to help fill up the seal-chute, so as to prevent another'seal being; inserted while one still remains in the slot-way. Each seal maybe provided at its" leading end with a hole 133', for convenience in carrying a number ofseals upon a wire or a hook.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
